1. A catheter sheath device comprising:
an elongate member, at least a portion thereof configured to be insertable into a body of a patient, the elongate member comprising a proximal end portion and a first lumen extending within and extending from the proximal end portion of the elongate member; and
a moveable member physically coupled to the proximal end portion of the elongate member to permit relative movement therebetween,
wherein the catheter sheath device is manipulable into a first configuration of engagement with a catheter, the first configuration of engagement configured to physically constrain the catheter with respect to the catheter sheath device, and the first configuration of engagement configured to provide the catheter no access to the first lumen,
wherein the catheter sheath device is manipulable into a second configuration of engagement with the catheter, the second configuration of engagement configured to provide the catheter with access to the first lumen, and
wherein the moveable member is configured, via being physically coupled to the proximal end portion of the elongate member to and via a relative movement between the moveable member and the proximal end portion of the elongate member, to reposition the physically constrained catheter from the first configuration of engagement into the second configuration of engagement that is configured to provide the catheter access to the first lumen, the first lumen configured to receive at least part of the catheter in the second configuration of engagement.
